Request: symbolic manipulation on select part

[compsystems]

Currently you can select part of an expression in the input line [shift + view] then [begin..end], but you can not manipulate it symbolically as it does xcas and other cas.

My request is that in the menu

[begin] [end] [] [all] [cut] [copy]

Include a menu for symbolic manipulation

[begin] [end] [Symbolic] [all] [cut] [copy]

where for example symbolic has several submenus: simplify, normal, factor, approx, eval

(x-2)^2*(3*x-1)

[symbolic]

(x^2-4*x+4)*(3*x-1)

So a bit like the [ALGEBRA][FORM] menu from the HP28C/S which morphed into the [EQUATION][RULES] menu on the HP48SX/GX but then got dropped from the 49 and 50, unfortunately.
